Oil burner

OIL BURNER.

IAJSLQTU,

Application filed May 29,

To all whom it may can own.

Be it known that I, WILLIAM A. Mars, a citizen of the United States, residing at Austin, in the county of. Travis and State of Texas, have invented new and useful Improvements in Oil Burners. of which the following is a specification.

One object of my present invention is the provision of a simple, compact and eflicient oil burner of self-cleaning and reversible capacity.

Another object is the provision of an oil burner embodying an oil tube that is susceptible of being quickly and easily removed from the burner body when occasion demands and as readily replaced without the necessity of disturbing the other elements of the burner.

Other objects and practical advantages of the invention will be fully understood by the following description and claims when the same are read in connection with the drawings, accompanying and forming a part of this specification, in which Figure 1 is a longitudinal section illustrating the burner that constitutes the best practical embodiment of my invention of which I am cognizant.

Figure 2 is a section taken in the plane indicated by the line 2-2 of Figure 1 looking toward the outer end of the burner.

Figure 3 is an elevation showing the outer end of the burner.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The body of my novel burner is preferably, though not necessarily, of general "2'- configuration, and is preferably made up of a tubular section 1, detachably connected at 2 to a head section 3. I would have it understood, however, that it is within the pur- View of my invention to either make the body in one piece or in any desired number of sections. 7

The tubular portion 1 of the body is provided, by preference in its forward portion with spiral grooves 4, the function of which is to impart to the steam a whirling motion.

In the wall 5 which intersects the longitudinal bore of the body is a threaded seat 6 for the engagement of the correspondingly threaded enlargement 7 at the outer open end of the oil tube 8 which is preferably of the proportional length illustrated. The said enlargement is provided with an inte- Specification of Letters Patent.

rior 9, of angular form in cross section, so that when the cap 10 is removed, the oil tube 8 may be expeditiously and easily removed through the medium of any appropriate implement arranged in the angular interior 9. At its inner side the cap 10 is provided with a gasket 11 of any appropriate material, and it will be noted by reference to Figure 1 that the nipple 12 on which the cap 10 is screwed is so arranged that the gasket 11 is spaced from the end of the tube 8, and the tube enlargement 7 is spaced from the inner side of the said nipple 12.

At opposite points in its head portion e the body of the burner is provided with threaded sockets l3 and 14 for the connection of an oil supply pipe and a steam supply pipe, respectively. Extending between the said sockets 13 and 14: are bores 15 and 16, the said bores being preferably arranged in parallel relation and intersecting the main longitudinal bore of the body as illus trated. I

Suitably secured in the head portion of the body are valve plugs 17 and 18 in each of which. is a preferably diametrical port 19.

In the practical use of my novel burner it will be manifest that when the parts are positioned as shown in Figure 1, and oil is supplied to the point 13 and steam to the point 14, the oil will pass through the outer portion of the bore 15, the. port 19 of valve 17 and the inner port-ion of the bore 16 to the inner end of the tube '8, and will then pass through the full length of the tube 8 to the eduction point thereof. At the same time the steam will pass through the outer end portion of the bore 16, the port 19 of valve 18 and the inner portion of the bore 15 to the main longitudinal bore of the burner through which it will pass to and beyond the eduction point of the tube 8 so that the steam will have a suction effect in the feed or supply of oil. As it escapes from the burner the steam will be given whirling motion by the spiral grooves 4 as will the oil commingled with the steam with the result that a highly combustible mixture will be supplied by the burner.

It will be manifest from the foregoing that following the removal of the cap 10 any appropriate instrument may be passed through the tube 8 to clear the same, or if desired the tube 8 may be readily removed for repairs or to give place to a new tube which may be as readily secured in the body,

and this without disturbing the other parts of the burner.

It will also be manifest that in cold weather when the oil is thicl; and heavy a proper feed of oil may be attained by reversing the valves 1.? and 18 so that steam will be supplied to the inner end of the tube 8 while oil is supplied tl'irough the main longitudinal bore of the burner body. Again, it will be noted that when the tube 8 becomes clogged with sediment the supply of oil may be cut off by the manipulation of the valve 1? or preferably by the closing 0'] a globe valve (not shown) in the oil supply pipe, whereupon the valve 18 may be adjusted to send a jet of steam through the tube 8 to clear the latter.

It will be apparent from the foregoing that in addition to the practical advantages hereinbefore ascribed to my novel burner, the burner as a whole is simple and compact in construction and is well adapted to withstand the usage to which hydrocar bon burners are ordinarily subjected.

An important characteristic of my invention resides in the fact that the valve plugs have the capacity of being placed in three distinct positions, in one position to lead fluid from the outer transverse bore 'to the inner transverse bore, to lead Fluid from the inner transverse bore to the outer transverse bore, and to positively close both or the transverse bores when the burner'is not in use Having described my invention, what I claim and desire to secure by Letters-Patent,

1. A. burner comprising a body having a longitudinal main bore and also having an outer threaded nipple together with inlets for oil and steam, respectively, and bores arranged in parallelism and at right angles to the main longitudinal bore and extending between said inlets; an oil tube open at its ends and having a threaded outer end enlargement detachably secured in the body and disposed within and spaced from the wall of the nipple and also having the outer end portion of its interior of angular form in cross section; a cap removably arranged on the threaded nipple; and valve plugs each having a diainetrical port to effect connection between the bores intermediate of the oil and steam inlets, said valve plugs being mounted and capable of being turned about their axes in the body.

2. An oil burner having a main longitudinal bore and an oil conduit arranged in said bore and spaced from the wall thereof and open at its rear end to the interior of the body and also having inlets for oil and steam, respectively and bores between said inlets and in communication with the main longitudinal bore and the rear portion of the oil conduit, respectively, and valves each having a port to efl ect direct connection between the said intermediate bores, said valves being adjustable to selectively'control the bores.

3. An oil burner comprising a body having a main. longitudinal bore and a wall opposed to the outer end of said bore in which wall. isa tapered, threaded aperture, and also having a nipple outwardly beyond said wall and alinedwith said aperture, an oil tube open at its outer end and having its interior at said end of angular form in cross section, and also having an intermediate tapered and threaded portion seated in said aper ture, and closure means detachably con nected to said nipple.

4t. An oil burner having a main longitudinal bore and an oil tube therein and open at its outer end and also having inlets for oil and steam, respectively, and adjustable apertured plugs each intersecting two of said inlets and each arranged in one position to close its respective inlets, whereby either oil or steam may be supplied to either the main longitudinal bore Or the oil tube or either steam or oil may be supplied while the other is cut ofi. i

In testimony whereof I afiix my signature.
